Researchers from Nottingham University in the United Kingdom have developed a new method for reducing the level of contamination of chickens by the foodborne bacterium Campylobacter jejuni. They are using bacterial viruses to target and kill the organism. They report their research today at the 104th General Meeting of the American Society for Microbiology.
In the study, the researchers isolated a number of naturally occurring bacterial viruses (called bacteriophage) that can infect and kill campylobacter bacteria from the feces of chickens. They then used these bacteriophage to treat chickens that were infected with campylobacter.
"Campylobacter bacteriophage are naturally present in chickens and have no recorded detrimental effect on the health of chickens or human beings," says Catherine Loc-Carrillo, a researcher on the study. "In nature a balance exists between predator and prey which allows both [the bacterium and the bacteriophage] to flourish. Here the use of bacteriophage to reduce campylobacters within the chicken gut merely involves shifting natures balance in our favor for a short period of time. This time point should be just prior to when the birds are sent for slaughter."

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
